Has any one tried the aFe Silver Bullet Throttle Body Spacer (46-34011)

Proxses

Won't do anything worthwhile.
It's an incredibly small change in manifold volume, which could have an effect on throttle response. But not enough to warrant the purchase in this case.

The dyno numbers look good at the upper end but lower end looks unusual.

Ive never found those spacers to do much

Waste of money.

You'll get more response and effect from a ported TB than a spacer.

Q8 c7

Maybe the tb has better response,but why the does the rpm take a while to go down when i rev?as if the rpm lags

Theta

That's just going to be the normal RPM fall time for the engine. The only way to decrease that is with a lighter flywheel, etc.

Q8 c7

Oh ok great,so i dont have a problem with my tb...i tried to order this spacer,but they dont have international shipping,so i tired to order it through myus.com but they dont have paypal either

Q8 c7

Wont the spacer help any tiny bit?

Speaking from the viewpoint of the past threads here and on countless other LSx forums, they don't do anything for you.

One example on an LS3 (61 pages ): http://www.camaro5.com/forums/showthread.php?t=228990

You can try it, but I wouldn't expect much.

You would see allot more benefit from simply keeping gas tank half full and stopping for fuel more often - no joke, and it’s free! Same goes for ported TB, another waste of money.

Theta

That actually isn't true, at least with a blower. It's quite noticeable in throttle response as with all LSx TB port jobs.

Been there done that, my seat of the pants dyno is different than yours . Yes it seems more responsive but does not equate to actual dyno numbers, no noticeable times i.e. 60+ MPH pulls using GPS v-box.

Again lose some weight (less fuel, simple example) will net you way more and free LOL.



EDIT - what you feel is blower and not TB...
